OIL BURNER.

Application filed November 2a, 1923. Serial No. 676,375.

To all whom it may concern:

Be it known that we, ANTON LIJESKE and FRANK BALCERZAK, both citizens ofthe United States, and residents of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and usefulImprovements in Oil Burners; and we do hereby declare that the followingis a full, clear, and exact description thereof.

This invention relates to oil burners and is particularly directed to anoil burner adapted to be positioned within a furnace such for instanceas the, domestic type of furnace, although the burner may be used inother capacities.

Objects of this invention are to provide an oil burner in which smallsupply nozzles or tiny apertures for the delivery of oil will beavoided, in which a large delivery opening is provided and is yieldinglyclosed by a valveadapted to prevent the entrance of scale or trash whichmay fall upon such delivery portion, and which insures an evendistribution of oil completely around the delivery portion.

Further objects are to provide an oil,

burner in which a burner plate is provided for permitting any desiredrate of combustion, in which an air preheating shell devoid ofrelatively constr cting air passages is provided, and in which aplurality of flame baffles or deflector members are provided,

which may be independently removed or renewed without disturbing otherportions of the burner.

Further objects are to provide an oil burner in which the parts areformed from simple castings and in which the parts are so constructedthat machine work is avoided and attaching bolts are not required, but

instead in which the successive portions are formed with interengagingparts so that they may be most readily assembled and removed -forcleaning or removal.

An embodiment of the invention is shown in the accompanying drawings, inwhich Figure 1 is a vertical sectional view through the burner.

Figure 2 is a horizontal sectional view entire line 22 of Figure 1.

. Figure 3 is a plan view of the burner" plate and a portion of thebase.

The oil burner comprises a base which consists of a centrally locateddisk 1 provided with an upstanding rib 2 and supported by means of aplurality of radial y extending spokes 3 from an outer ring 4. Thisouter ring 4, as may be seen from Figure 3, is provided with a pluralityof inwardly projecting lugs or cars 5. The centrally located disk 1 isprovided with upstanding projections 6 upon which a burner plate isadapted to rest. The burner plate 7 is a separate and distinct castingand consists of a circular disk like member provided with a centrallylocated upstanding standard 8 which has a centrally located hole 9therethrough. If desired, this standard may be provided with an enlargedrecessed upper portion adapted toreceive the disk 10 of a valve whosestem 11 loosely fits within the hole 9 therethrough. This.

burner plate is further provided with a series of concentric ribs 12which surround the standard 8 and form a series of grooves insuccessively elevated tiers. A convenient way of attaching the burnerplate to the disk 1 of the base is by means of a threaded nipple 13, asillustrated in Figure 1,the disk 1 being centrally apertured andreceiving the supply pipe 14. The outermost .of the grooves formed inthe burner plate.

of the outer'wall resting within the outer ring 4 and upon the lugs 5.The inner and outer cylindrical walls are integrally joined by a topportion 19 which is provided with an annular rib 20. It is to be notedthat th inner cylindrical member is provided with a constricted portion21. A plurality of similar deflectors 22 are positioned one above theother and above the central passageway through the cylindrical member18. These deflectors are provided with downwardly projecting legs23,-the lowermost of such egs restin upon the top portion 19 of the mainshel and being held in position by means of the rib 20. It is to benoted that the top of each of these legs is flat and pro vides ashoulder u on which the leg 23 of the succeeding mem er ma rest. It isto be tially dome shaped and thus positions the 'legs 23 of successivemembers and retains them against lateral mot-ion. These deflectors arepreferably apertured and the apertures of successive eflectors arearranged in stagger relation. It is to .be understood that as manydeflectors as needed may be employed as it is merely necessary to standone upon the other.

The operation of the apparatus is as follows :Oil is supplied throughthe feed pipe 14 and the combustion is started in any desired manner.The oil flows upwardly throu h the hole 9 in the standard 8 and slight yraises the valve 10. This valve, it will be noted, causes the oil touniformly flow over the entire upper marginal edge of :the standard 8and thus causes a sheet of oil to flow downwardly over the outer surfaceof such standard and into the first groove. Thereafter, any oil that isnot consumed at this point flows over into the next groove and if itshould happen that all of the oil has not yet been consumed, suchremainin oil will flow to the outermost groove. I for any reason, thefire should go out, the oil in the outermost groove will flow into theoverflow pipe 15 and actuate any of the usual automatic cutofi devices.

It is to be noted that the pipe 15 projects above the bottom of theoutermost groove so that such outermost groove may be used as one of thegrooves for holding oil, which is being burned in the same capacity asany of. the other grooves independently of the overflow functionfurnished by the pipe 15, as such device does not function or p ay'anypart in the operation of the burner until the height 'of the oil in theoutermost groove exceeds a predetermined value.

It is to be noted that the air passes upwardly freely between the ring 4and the centrally located dislf 1. It is guided between the cylindricalmember 16 and the cylindrical wall 17 of the enclosing shell.v

It is preheated, as these parts actively absorb heat in the normaloperation of the burner, and is deflected downwardly by the innercylindrical member or wall 18. The preheated air then flows across theburner plate and towards the center thus picking up vaporized oil andentering into the combustion thereof. The products of combustion passupwardly through the interior of the cylindrical portion 18 and upwardlythrough the constricted portion, such constricted portion insuring arapid travel of the burning gases and causing a smokeless flame to beprojected upwardly beyond the outer shell. This flame is not allowed tocontact directly with the furnace walls but strikes the deflectors 22and asses laterally therefrom and alsoupward y through the apertures.The staggered arrangement of successive apertures prevents any tonguesof it will be noted, prevents any falling scale or trash' from enteringthe hole 9 ceritrally located standard 8. t will further be seen thateach of the several parts composing the burner may be most readily castas the are of simple formation and do not require elaborate mouldingoperations for their production.

It will further be seen that the successive grooves formed as distinctentities'in the in the burner plate permit any rate of combustion withinthe limits of the apparatus to be attained, that is to say, if a smallamount of oil only is supplied the device, such oil will be'distributedover the central standard and will fill only the first of the concentricgrooves evaporating at this point, burning, and mixing with the heatedair. If a greater flow of oil is given the device the next groove willalso fill with oil and a more extensive burning oil surface will bepresented to the incoming highly heated air.

1 Obviously, the number of grooves could be varied to provide anapparatus of any desired capacity.

Although the invention has been described in considerable detail, it isto be understood that the invention may be variously embodied and is,therefore, to be limited only as claimed.
